ABSTRACT:
A packaging bag for containing a product is provided. The bag includes an end with four bag projections that are to be folded over the product. A first pair of opposing bag projections are folded down to form generally triangular portions, and the other pair of opposing bag projections are folded onto the triangular portions and connected together in the overlap area while basically maintaining their rectangular shape and catching the corners of the first pair of bag projections. In order for the first pair of bag projections to be formed along the long side of the bag, the fold edges between adjacent bag projections run at least partially outside of the contour of the bags when folded and the angle formed between the side and base of the triangular portion when folded in is less than 45.degree..
